[Pljava-dev] LargeObject

Shunsuke,
The LargeObject support in PL/Java is experimental and in the current
version, the C-code will not be initialized (hence the error that you
get). The code is there though, and if you want to play around with it,
my guess is that the only thing you need to do in order to get it to
work is to add the line:

LargeObject_initialize(fcinfo);

somewhere near the end of function Type_initialize in the file
pljava/type/Type.c, recompile and try again.

Regards,
Thomas Hallgren
